This study assessed the ability of the extended Theory of Planned Behavior (TPB) to account for motorcyclists' intentions to comply with the school zone speed limit (SZSL) in 2 specific scenarios: presence of other drivers driving and the presence of school children in a school zone. A sample of motorcyclists (N=634) was surveyed with a questionnaire constructed to measure attitudes toward behaviors, subjective norms, perceived behavioral control, habit, personal norm and behavioral intentions. Results showed that the scenarios affect the motorcyclist attitude, habit and personal norm. In particular, with the presence of school children in a school zone, attitude and personal norm became significant predictors of intention to comply. In contrast, with the other drivers driving in the school zone and no school children around that area, attitude and habit were the significant predictor towards intention to comply. The relation between attitude and behavioral intentions was consistently stronger between the two scenarios.
